Workers have won their legitimate rights and interests with indomitable heroism through struggle, which is a historic progress of human civilization and democracy and a * * * festival for the proletariat and working people all over the world.

International Labor Day, also known as "May 1 International Labor Day" and "International Demonstration Day", is a national holiday in more than 80 countries in the world. On May 1 day every year. This is a festival for working people all over the world.

1884 in June, eight international and national workers' groups in the United States and Canada held a rally in Chicago, USA, and decided to hold a general strike on May 1886, forcing capitalists to implement an eight-hour working system. This day has finally arrived.

On May 1 day, 350,000 workers from more than 20,000 enterprises in the United States stopped working and took to the streets to hold a large-scale demonstration. Workers of all colors and jobs went on a general strike together. In Chicago alone, 45,000 workers poured into the streets.

On May 3, the Chicago authorities finally tore off the mask of "democracy" and suppressed the workers with violence. They organized strikers to sneak into the workers' strike team under the protection of the police, deliberately creating chaos and using this as an excuse to shoot and kill six workers on the spot. This atrocity aroused the great indignation of the workers in the city, and they were determined to avenge the dead workers' brothers!

In order to commemorate this great workers' movement, 1889, in July, at the Second International Founding Congress organized by Engels, it was announced that May 1 day every year would be designated as International Labor Day, referred to as "May Day" for short.
